A letter or a lawsuit from "Stern & Eisenberg" is unsettling because it comes from a law firm, not a call center. The short version: it's a real, established creditors'-rights firm, not a scam. The version that protects you is that a lot of this firm's work is mortgage and foreclosure -- secured debt you handle very differently from a credit card.
Short answer
Yes, Stern & Eisenberg is legit -- a multi-state law firm that represents lenders, servicers, and banks, with a heavy default-mortgage and foreclosure practice. Figure out what kind of debt it is first: a mortgage is secured and handled through loss mitigation, not settlement.
Who they are
Stern & Eisenberg is a creditors'-rights law firm based in Pennsylvania that works across several mid-Atlantic and Northeast states. Its practice areas center on default mortgage servicing, foreclosure, evictions, and bankruptcy-creditor work, along with general litigation. When it contacts you, it is acting on behalf of a lender or servicer -- so the first question is always whether the account is secured (your home) or unsecured.
If it's about your mortgage (secured)
A mortgage is secured by your house, so no debt-relief or settlement program can negotiate it away like a credit card. The tools that actually help are loss mitigation: a loan modification, forbearance, repayment plan, or reinstatement through the servicer. Talk to a HUD-approved housing counselor -- their help is free -- and consider a foreclosure-defense attorney. Never pay an upfront fee to anyone who promises to stop a foreclosure.
If it's an unsecured account
If the firm is pursuing a charged-off credit card or a deficiency balance, treat it as summons-first. File a written answer by the deadline -- ignoring a summons invites a default judgment and then garnishment or a bank levy. Then demand written validation, and if a debt buyer is suing, require the chain of title plus an itemized balance. Attorneys are not exempt from the FDCPA, and a lawyer can't seize anything until a court enters judgment.
Is it a scam?
No -- it's a real firm. But impostors borrow official-sounding names and demand gift cards or wires with threats. A real firm names the case and the court and takes traceable payment. Confirm any lawsuit actually exists on the court docket, and check the statute of limitations before you engage -- a payment can restart it.
If it's unsecured, validated, and yours
Once it's confirmed unsecured, validated, and genuinely owed, it's negotiable. You can settle in writing, ideally before judgment, and always get the terms in writing before you pay. A forgiven balance over $600 may generate a 1099-C. Keep proof. Foreclosure and court rules vary by state.
